从1999年元月1日起,北京市将执行新的“轻型车排气污染物排放标准”。这是一项我国最严格的地方性汽车排放标准。作为国际大都市,明年绝大多数化油器轻型汽车将被淘汰出首都。毫无疑问,这一举措将大大加速我国汽车使用电喷发动机及三元催化净化器的进程。 起净化汽车排气作用的三元催化净化器,能在效地把排气中的有害成份XOx、CO、HC转化成无一毒的水蒸气、氮气和二氧化碳。它装 From January 1, 1999 onwards, Beijing will implement the new “Light Vehicle Exhaust Pollutant Emission Standards.” This is one of the most stringent standards of local car emissions. As an international metropolis, next year most of the carburetor light vehicles will be eliminated from the capital. Undoubtedly, this measure will greatly accelerate the process of using EFI engines and three-way catalytic converters in China’s automobiles. The three-way catalytic converter that purifies the exhaust of vehicles can effectively convert the harmful components XOx, CO and HC in the exhaust gas into non-toxic water vapor, nitrogen and carbon dioxide.
